However, since various shapes of the ice-making units 9 and 10 can not be formed, only the same circular ice can be manufactured, which is inconvenient for the user to be bored due to monotony.

Further, when the heat exchanging part 11 formed with the refrigerant inflow pipe and the refrigerant discharge pipe is coupled to the outer edge of the ice making unit 9 and 10, the free flow of the refrigerant between the heat exchanging part 11 and the ice making unit 9 and 10 The heat exchanging part 11 is welded to the outer edge of the ice making unit 9 and 10 so as to seal the duct part. At this time, since the heat exchanging part 11 is formed in a 'C' shape and its open end is joined to the outer edge of the ice making unit 9 and 10 by simple welding, the free channel part is not sealed properly, Respectively. In addition, there is a problem in that ice can not be easily produced because the ice-making is not properly performed due to the leakage of the refrigerant.

The condenser 10 condenses the refrigerant.

The refrigerant passing through the condenser line 30 is condensed in the condenser 10 by the condenser 10, so that the refrigerant is condensed by the condenser 10.

The compressor (20) compresses the vaporized refrigerant.

The condenser line (30) conveys the refrigerant compressed in the compressor (20) to the condenser (10).

The refrigerant line (40) conveys the refrigerant condensed from the condenser (10) to the compressor (20).

That is, since the condenser 10, the compressor 20, the condenser line 30 and the refrigerant line 40 are known to be conventional, detailed description thereof will be omitted.

The ice-making water nozzle unit (50) discharges ice-making water.

The lower portion of the ice-making water nozzle unit 50 is divided into a plurality of branch pipes 52 so that the ice-making water can be discharged toward the inner peripheral surface of the ice-making water supply pipe 60. That is, the inlet of the branch pipe 52 preferably faces the inner peripheral surface of the ice-making water supply pipe 60.

Thus, the ice-making water falls down along the inner peripheral surface of the ice-making water supply pipe 60 and is ice-cooled on the inner peripheral surface of the ice-making part 70 by the coolant.

The ice-making water supply pipe (60) drops ice-making water discharged from the ice-making water nozzle portion.

4 is a cross-sectional view illustrating a guide member of an ice maker capable of manufacturing various shapes of ice according to a preferred embodiment of the present invention.

Referring to FIG. 4, an ice maker capable of manufacturing various shapes of ice according to the present invention further includes a guide member 80.

In addition, the outer member 74 has a refrigerant inlet portion 78 and a refrigerant outlet portion 79 formed on one side and the other side thereof.

The refrigerant passage portion 76 is formed so that the refrigerant flows along the outer circumferential surface of the inner member 71 because the outer circumferential surface of the inner member 71 and the inner circumferential surface of the outer member 74 are spaced apart from each other.

The refrigerant in the refrigerant passage portion 76 is moved smoothly along the outer peripheral surface of the inner member 71 of the inner member 71 so that the refrigerant is directly and directly applied to the deicing water passing through the inner portion of the inner member 71 The deicing water is de-iced.

That is, the ice-making unit 70 is disposed between the condenser 10 and the compressor 20, and is disposed in the middle of the refrigerant moving from the condenser 10 to the compressor 20. The refrigerant flows into the refrigerant inflow portion 78, moves through the refrigerant passage portion 76, and is discharged to the refrigerant discharge portion 79. At this time, the ice-making water passing through the inside of the inner member 71 of the ice-making unit 70 is heated by the refrigerant, and the ice-making water passing through the inside of the inner member 71 is de-iced.

Here, the inner member 71 and the outer member 74 are made of a single plate member and integrally formed.

A sealing portion is provided between the inner member (71) and the outer member (74) so that the refrigerant does not flow out from the refrigerant passage portion (76).

The closed portion is configured such that both the upper and lower portions of the outer member 74 except for the portion constituting the refrigerant passage portion 76 are in surface contact or line contact with the outer peripheral surface of the inner member 71. [ To this end, the sealing portion prevents surface leakage or refrigerant leaking by welding to the surface-contacting portions.

6 and 7, the inner member 71 made of one plate is formed to have a specific shape by drawing processing.

The specific model formed on the inner member 71 consists of either a star model, a heart model, or a polygonal model.

In other words, since the internal cross-section of the inner member is formed by a model of a star model, a heart model, and a polygonal model by making a specific model, various ice models can be formed when deicing ice water, (See FIG. 7).

The outer shape of the outer member 74 surrounding the inner member 71 is preferably formed such that the refrigerant flow path portion 76 has the same spacing in all directions with respect to one end face of the inner member 71. The outer member 74 may be formed to have a specific shape by drawing processing.

It is also preferable that the ice formed inside the inner member 71 is separated from the inner member 71 through heat generated in the heat supply portion (not shown) through the refrigerant passage portion 76.

Here, the heat supply unit is provided inside or outside of the ice making unit 70 so that the ice generated by heating the ice making unit 70 can be separated, but is not limited thereto. For example, the heat supply unit may be composed of hot wire or hot gas.
